Intended Use
For in vitro diagnostic use. FLEX Monoclonal Mouse Anti-Human Progesterone Receptor, Clone PgR 1294, Ready-to-Use (Dako Omnis), is intended for use in immunohistochemistry with the En Vision FLEX visualization system together with the Dako Omnis instrument to qualitatively detect human progesterone receptor in formalin-fixed, paraffin-embedded tissue sections of human breast cancer. The antibody binds progesterone receptor-expressing cells and is useful in the assessment of progesterone receptor status in human breast carcinomas. The clinical interpretation of any staining or its absence should be complemented by morphological studies using proper controls and should be evaluated within the context of the patient's clinical history and other diagnostic tests by a qualified pathologist. This antibody is intended to be used after the primary diagnosis of tumor has been made by conventional histopathology using nonimmunologic histochemical stains.
Device Description
FLEX Monoclonal Mouse Anti-Human Progesterone Receptor, Clone PgR 1294, Readyto-Use (Dako Omnis) is utilized to perform a qualitative immunohistochemical (IHC) assay to identify progesterone receptor (PR) expression in formalin fixed human breast cancer tissues routinely processed and paraffin-embedded for histological examination. The proposed device is a variant of FLEX Monoclonal Mouse Anti-Human Progesterone Receptor intended for use with the automated slide staining instrument Dako Omnis. The design of the proposed device is developed to provide equivalent performance to its predicate FLEX Monoclonal Mouse Anti-Human Progesterone Receptor, Clone PgR 636, Ready-to-Use, (Link) with adaptation of the product configuration, to be used on the Dako Omnis Instrument instead of the Autostainer Link 48 Instrument. The antibody is provided in liquid form in a buffer containing stabilizing protein and 0.015 mol/L sodium azide. The proposed device is intended for automated immunohistochemical (IHC) slide staining with the Dako Omnis Instrument and the software performing and controlling the automated slide staining process is validated for its intended use.
More Information

Not Found

No
The summary describes an antibody and an automated staining instrument for immunohistochemistry. There is no mention of AI or ML being used for image analysis, interpretation, or any other function. The software mentioned controls the staining process, not image analysis.

No
The device is an in vitro diagnostic (IVD) used to detect progesterone receptor in tissue samples, aiding in the assessment of breast cancer, which is a diagnostic purpose, not a therapeutic one.

Yes

Explanation: The "Intended Use / Indications for Use" section explicitly states, "For in vitro diagnostic use." The device is used to qualitatively detect human progesterone receptor in tissue sections, which aids in the assessment of progesterone receptor status in human breast carcinomas, a key diagnostic step in cancer treatment.

No

The device is a reagent (antibody) used in an in vitro diagnostic process, not a software-only medical device. While it is used with an automated instrument and its software, the device itself is a physical substance.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Explicit Statement: The "Intended Use / Indications for Use" section begins with the clear statement: "For in vitro diagnostic use."
  • Purpose: The device is intended to "qualitatively detect human progesterone receptor in formalin-fixed, paraffin-embedded tissue sections of human breast cancer." This is a diagnostic test performed on biological samples (tissue sections) outside of the living body.
  • Clinical Context: The description emphasizes that the results are for "assessment of progesterone receptor status in human breast carcinomas" and that the "clinical interpretation... should be evaluated within the context of the patient's clinical history and other diagnostic tests by a qualified pathologist." This highlights its role in the diagnostic process.
  • Method: The device utilizes immunohistochemistry (IHC), a common in vitro diagnostic technique.

All of these points align with the definition of an In Vitro Diagnostic device.

§ 864.1860 Immunohistochemistry reagents and kits.

(a)
Identification. Immunohistochemistry test systems (IHC's) are in vitro diagnostic devices consisting of polyclonal or monoclonal antibodies labeled with directions for use and performance claims, which may be packaged with ancillary reagents in kits. Their intended use is to identify, by immunological techniques, antigens in tissues or cytologic specimens. Similar devices intended for use with flow cytometry devices are not considered IHC's.(b)
Classification of immunohistochemistry devices. (1) Class I (general controls). Except as described in paragraphs (b)(2) and (b)(3) of this section, these devices are exempt from the premarket notification requirements in part 807, subpart E of this chapter. This exemption applies to IHC's that provide the pathologist with adjunctive diagnostic information that may be incorporated into the pathologist's report, but that is not ordinarily reported to the clinician as an independent finding. These IHC's are used after the primary diagnosis of tumor (neoplasm) has been made by conventional histopathology using nonimmunologic histochemical stains, such as hematoxylin and eosin. Examples of class I IHC's are differentiation markers that are used as adjunctive tests to subclassify tumors, such as keratin.(2) Class II (special control, guidance document: “FDA Guidance for Submission of Immunohistochemistry Applications to the FDA,” Center for Devices and Radiologic Health, 1998). These IHC's are intended for the detection and/or measurement of certain target analytes in order to provide prognostic or predictive data that are not directly confirmed by routine histopathologic internal and external control specimens. These IHC's provide the pathologist with information that is ordinarily reported as independent diagnostic information to the ordering clinician, and the claims associated with these data are widely accepted and supported by valid scientific evidence. Examples of class II IHC's are those intended for semiquantitative measurement of an analyte, such as hormone receptors in breast cancer.
(3) Class III (premarket approval). IHC's intended for any use not described in paragraphs (b)(1) or (b)(2) of this section.
(c)
Date of PMA or notice of completion of a PDP is required. As of May 28, 1976, an approval under section 515 of the Federal Food, Drug, and Cosmetic Act is required for any device described in paragraph (b)(3) of this section before this device may be commercially distributed. See § 864.3.
